Abstract (en)
[origin: US4364395A] A shunt system for implantation in the body which can be used for transferring cerebrospinal fluid is disclosed. The shunt system comprises a body having an upper and lower surface and a distal and proximal end. The body includes a central cavity opening through the upper surface at a first and second port. A proximal fluid flow channel extends through the proximal end of the body and opens at a third port on the upper surface. A distal fluid flow channel extends through the distal end of the body and opens at a fourth port on the upper surface. A resilient dome comprised of a self-sealing material is attached to and extends over the upper surface of the body. A first portion of the resilient dome extends over the first and third ports on the upper surface defining a first chamber. The first portion of the resilient dome cooperates upon flexing with the third port to occlude the third port. A second portion of the resilient dome extends over the second and fourth ports on the upper surface defining a second chamber. The second portion of the resilient dome cooperates upon flexing with the fourth port to occlude the fourth port.
